Business Employment Dynamics is
a set of statistics generated from the Quarterly Census of
Employment and Wages program. These quarterly data
series consist of gross job gains and gross job losses statistics
from 1992 forward. These data help to provide a picture of the
dynamic state of the labor market.

Hurricanes Irma and Maria made landfall in the United States on September 7 and September 20, 2017, respectively, during the QCEW third quarter reference period. These events did not cause changes to QCEW methodology. However, they did affect data collection in Puerto Rico and the U.S. Virgin Islands. For more information, please visit this webpage: www.bls.gov/bls/hurricanes-harvey-irma-maria.htm.

With the processing of fourth quarter 2014 BED data, BLS implemented a new statistical matching process used in
the longitudinal linking of Quarterly Census of Employment and Wages (QCEW) data. Tabulations from this quarter
forward will reflect this new methodology. For additional details on this new methodology, please see the article "A
Simplified Approach to Administrative Record Linkage in the Quarterly Census of Employment and Wages"
available at: http://www.bls.gov/osmr/pdf/st140020.pdf.

Additionally, all historical BED series back to third quarter 1992 have been revised with the release of first quarter 2015 data, for both seasonally adjusted and not seasonally adjusted series, to incorporate an administrative change in scope. These revisions are primarily due to the reclassification of a number of establishments from private households (NAICS 814110) to services for the elderly and persons with disabilities (NAICS 624120). Private households are not within the scope of BED and, as a result, those establishments impacted by this industry reclassification are now within scope.
